Interface TriggerRuntimeMBean

All Superinterfaces:

DynamicMBean, MBeanRegistration, NotificationBroadcaster, RuntimeMBean, WebLogicMBean

public interface TriggerRuntimeMBean
extends RuntimeMBean

The TriggerRuntimeMBean holds runtime state (for the current Server instance) for a Trigger that has been configured in the Resource Consumption Management policy of the current Domain Partition.

The WebLogic Resource Consumption Management feature automatically initiates the configured recourse action of a Trigger when the Trigger's configured usage limits are exceeded by a Domain Partition. When a usage limit is exceeded, and the configured recourse action has been successfully executed, the Trigger is Activated.

When the current resource usage by the Domain Partition falls below the Trigger's configured usage limit, the feature automatically withdraws the recourse action where possible. When the current usage is below the configured usage limit, and the configured recourse action has been successfully withdrawn, the Trigger is said to be not Activated.

The MBean captures the following states for a Trigger when the current resource consumption usage by the Domain Partition exceeds or goes below the configured usage limit for the Domain Partition:

• Whether the Trigger is Activated (usage has exceeded the limit and the recourse action was successfully executed) or not
• The time when the last recourse action was executed successfully for the Trigger
• Whether a recourse action has been initiated in response to the resource usage by the Domain Partition exceeding the configured usage limits

Method Summary

Modifier and Type	Method and Description
Date	getLastTimeExecuted() The Date when the last recourse action was successfully executed for the current Trigger.
String	getName() The name of the Trigger, as configured in the Resource Consumption Management policy of the Domain Partition.
RecourseActionEventVBean[]	getRecourseActionEventsHistory() A list of recourse action events that have been initiated and executed.
boolean	isActivated() Indicates if the Trigger is Activated.
boolean	isInitiated() Indicates if a recourse action has been initiated for this Trigger as a result of the current resource usage by a Domain Partition exceeding its usage limit.

Method Detail

isInitiated

boolean isInitiated()

Indicates if a recourse action has been initiated for this Trigger as a result of the current resource usage by a Domain Partition exceeding its usage limit. A new RecourseActionEventVBean is added to the array returned by TriggerRuntimeMBean.getRecourseActionEventsHistory().

The kind of recourse action initiated (for example, a new recourse action or a withdrawal of an existing recourse action) can be determined through RecourseActionEventVBean.isActive().

Returns:

True, if an action has been begun in response to the current resource usage of the Domain Partition exceeding the usage limit set for that Partition. False, if no action has been initiated.

getName

String getName()

The name of the Trigger, as configured in the Resource Consumption Management policy of the Domain Partition.

Specified by:

getName in interface WebLogicMBean

isActivated

boolean isActivated()

Indicates if the Trigger is Activated.

Returns:

True, if the resource usage limit is exceeded by the Domain Partition and the configured recourse action has been successfully executed.

getLastTimeExecuted

Date getLastTimeExecuted()

The Date when the last recourse action was successfully executed for the current Trigger.

Returns:

The Date when the last recourse action was successfully executed for the current Trigger.

getRecourseActionEventsHistory

RecourseActionEventVBean[] getRecourseActionEventsHistory()

A list of recourse action events that have been initiated and executed.

Returns:

An array of RecourseActionEventVBean representing all the recourse action events that have been initiated, executed, and withdrawan by the WebLogic Resource Consumption Management feature for the current Trigger.
